An analysis of clinical features of pulmonary giant hydatid cyst in adult population
(Excerpta Medica Inc-Elsevier Science Inc, 2009)
BACKGROUND: We performed an analysis of giant hydatid cysts (GCHs) detected in the adult Population by comparison with the features of other simple hydatid cysts (CHs) in the light of the relevant literature. METHODS: The ...
New calculations of cyclotron production cross sections of some positron emitting radioisotopes in proton induced reactions
(Indian Assoc Cultivation Science, 2009)
In this study, new calculations on the excitation functions of C-13(p,n)N-13, N-14(p,alpha)C-11, N-15(p,n)O-15, O-16(p,alpha)N-13, O-18(p,n)F-18, Ni-62(p,n)Cu-62, Zn-68(p,n)Ga-68 and Ge-72(p,n)As-72 reactions have been ...
Application of asymmetry depending empirical formulas for (p,n alpha) reaction cross-sections at 24.8 and 28.5 MeV incident energies
(Pergamon-Elsevier Science Ltd, 2009)
In this study, we have investigated the asymmetry term effect for the (p,n alpha) reaction cross-sections and we have obtained new coefficients for the (p,n alpha) reactions at 24.8 and 28.5 MeV energies. We have suggested ...
A bicriteria parallel machine scheduling with a learning effect of setup and removal times
(Elsevier Science Inc, 2009)
In studies oil scheduling problems, generally setup times and removal times of jobs have been neglected or by including those into processing times. However, in some production systems, setup times and removal times are ...
A bicriteria parallel machine scheduling with a learning effect
(Springer London Ltd, 2009)
Conventionally, job processing times are assumed to be constant from the first job to be processed until the last job to be completed. However, recent empirical studies in several industries have verified that unit costs ...
The prediction of maximum temperature for single chips' cooling using artificial neural networks
(Springer, 2009)
A CFD simulation usually requires extensive computer storage and lengthy computational time. The application of artificial neural network models to thermal management of chips is still limited. In this study, the main ...
Clifford Product and Lorentzian Plane Displacements In 3-Dimensional Lorentzian Space
(Springer Basel Ag, 2009)
In this paper, by defining Clifford algebra product in 3-dimensional Lorentz space, L (3), it is shown that even Clifford algebra of L (3) corresponds to split quaternion algebra. Then, by using Lorentzian matrix multiplication, ...
Estimation of GHG Emissions in Turkey Using Energy and Economic Indicators
(Taylor & Francis Inc, 2009)
The greenhouse gas emissions (total greenhouse gas, CO2, CO, SO2, NO2, E (emissions of non-methane volatile organic compounds)) covered by the Kyoto Protocol are weighted by their global warming potentials and aggregated ...
Production and characterization of biosurfactants produced by microorganisms isolated from milk factory wastewaters
(Taylor & Francis Ltd, 2009)
Biosurfactants or surface-active compounds are produced by microorganisms. These molecules reduce the surface tension of both aqueous solutions and hydrocarbon mixtures. In this study, the isolation and identification of ...
Estimation of Net Energy Consumption in Turkey Using Different Indicators
(Taylor & Francis Inc, 2009)
The main subject in this study is to obtain equations to predict net energy consumption of Turkey using energy sources and economic indicators by artificial neural network approach in order to determine the future level ...
